Hi, we use Cloudflare tunnel which accept Github webhook into our internal network.
In many cases, it works fine, but sometimes(n times per day) Github recorded 200 status code with Cf-Ray ID response header and empty response body.
However, we cannot find any network trafiic from cloudflared to backend about it, and Cf-Ray ID was not recorded in cloudflared log.
Cloudflared is running with the below setting, so I think if some traffic come into cloudflared, it will be reorded in log.
- TUNNEL_LOGLEVEL: debug
- TUNNEL_PROTO_LOGLEVEL: debug
I wonder which component return Cf-Ray ID and 200 HTTP status and empty body.
I suspect Cloudflare or cloudflared.
